have now deployed my 4 boxes (4 x 1245v6, 64G), replacing a single Xeon-W 3235 (12 Cores) w/ 192G.
Went from single ESXi running via nfs / TNC box to a 4 node vSan Cluster
As expected power levels remained about the same (+-10% ) but o/c I gained a lot of redundancy (and a few spare cores).
Downside is that I am now short on memory since I didnt take into consideration that vSAN is using like 16GB per host, so basically 25% of my total memory driving me right into overutilization (with ~160G in use) ... which means I am not particularly redundant after all.
Maybe I can reduce vsan memory utilization by moving to 280GB Optanes from the 480 i now have, have not looked into it. Or need a fifth node.. but dont have 64g extra memory...
Edit - yes -> vSAN Memory consumption - are you kidding me
Anyhow, the boxes are running fine albeit a bit hot,
but o/c that one is quite busy
